I will start as an introduction as this is my first post. I played with Ubuntu in the 11-13 range. That was a long time ago and I decided to go in that direction to learn more about Debian and boycott OSX and Windows if I can. (Which will hopefully be 100% one day!)
Anyway, I have an old but golden 17 "Macbook Pro in early 2011, and since OSX is NOT SUPPORTED (although there is a looparound to make it work …), I chose Ubuntu 19.10 and eventually upgraded on April 20th when it comes out.
Now to my problem. This laptop has Intel HD Graphics 3000 and a Radeon HD 6750M.
When I tried to install Ubuntu LTS for the first time, a black screen was displayed immediately after pressing Enter on "Install Ubuntu". I then tried Ubuntu 19.10 and the same story there. So I did it with safe graphics mode and it worked! Which led me to believe that there was some kind of confusion with my graphics cards. I know that both graphics cards are in good condition, so it cannot be a hardware problem.
After installing Ubuntu in secure graphics mode, I encountered another problem. After the installation was complete, I was told to remove and restart my USB stick, and I did. The same thing had happened, and when I looked at it, I had to add a "# nomodeset" command to one of the lines in my Grub2. I started "Test Ubuntu in secure graphics mode" and chrooted my Grub2 root directory with the added line "nomodeset". This fixed my boot problem. Now I can boot and use my operating system almost perfectly. When I got on the system I did all the updates and upgrades and the computer works really well. Except for the graphics.
To my knowledge, the & # 39; nomodeset & # 39; line had disabled my ability to use a graphics driver. I have encountered a bug where the backlight does not turn on after waking up the device when I go into suspend mode. I can hear my audio being pushed up and down so I know the system is on but the backlight is off. But that's not a big problem for me.
I mainly want to use my dedicated AMD card to use 3D programs and possibly video games.
So that's the hard part.
How do I use my Intel card for normal tasks and switch to a graphics card if I use more sophisticated software? (To save battery, that's a big deal for me)
And since the & # 39; nomodeset & # 39; line is the only way to start the operating system, would installing the drivers fix the problem for me?
It looks like I already have the standard drivers for my Intel card and my Radeon card (Radeon uses Radeon drivers). In addition, no graphics cards are known on my "Additional Drivers" tab.
As I understand it, the nomode set must work, and my Intel card must be my default, and I also need a command to switch between the two GPUs.
If you got this far, thank you. I look forward to any advice. I worked on it for 1 day and it seems I haven't gotten anywhere yet. : D.
